I typically don't like romance (there are some exceptions) because I'm not a fan of soap opera in space.

If you think about it, a character not being in a romance, or some stage of one is somewhat unrealistic.

The Capatin might be the exception, but the majority of the people on board would have (or like Geordi, like to have) a person that they want to be with off duty. Seem that they would also have a circle of friend. Not have it be that everyone on board is equally your friend. Like Bashir and O'Brein, your close buddies.
Four stages of romance:
Inbetween romances.
Enter romance.
Immersed in romance.
Dissolving romance.
